To In whom it may concern Be it known that ll, Anemone B. JAMIsoN I a citizen ,of the United States, and a resident of the borough of Manhattan, in the city of New York, in the htate of New York, have invented certain new anduseful Improvements in Syringes, of which the following is a speci fication, reference being bad to the accompanylng drawings, forming a part hereof.

The weight of the water in the bag of a fountainsyringe is oftentimes found to bein suficient to effect the desired pressure or head at the tip end of the syringe, and it is not aid ways convenient or satisfactory to raise the bag high enough to obtain such'desired pressure or head, ,Furthermore, the weight of the water in the bag, especially when hot water is employed, soon destroys the bag, which in most fountain-syringes is made of soft rubber. Again, when the bag is not Wholly filled upwith water there is more or less air there in, which is often objectionable in the use of syringes of this type. v

lit is accordingly one of the objects of this invention to provide a fountaimsyringe which will be free from. the objectionable features just referred to;

Another object of the invention is to provide means in connection with a fountain-syriinge to impregnate the water used therein with oil, antiseptics, and other liquids without placing such liquids in the bag of the syringe and without obstructing the flow of water inthe apparatus.

V The invention will be merc fully described 7 hereinafter with reference tothe accompany ing drawings, in which I Figure 1 is anend view in elevation, and

Fig. 2 is a" side view in elevation, of the bag with improvements applied thereto. Figs, 3 and i, are similar views, respectively, showing amodificatlon of the improvements.

Tn both of'the forms of theinvention shown in, lliigs'.,,1 to t the bag a is supported inia pressure upon the bag.

frame comprising two side pieces 6 and 0, preferably flat, fastened together in any suitable mannerat one end, and a cord at, by which the apparatus is supported and which joins the other or free ends of the pieces 6 and 0.

Referring to Figs. 1 and 2, in which the preferable form of the invention is illustrated, the pieces 6 and 0 are hinged at the neck of the bag, which is supported at that end by said pieces coming together at the neck and by suitable fastening means, as a cord 6 extending through eyelet-holes f in the top of the bag, thus making three supports for the top of the bag. The cord at is preferably made endless and forms a loopy for supporting the apparatus from a hook or other sup port, the cord OZ extending down on each side of one of the side pieces ofthe frame and through said side piece at its lower end, pul leys it being provided for the cord to run on.

After passing the pulleys h the cord extends may be secured to the lower end of the side piece 5, whence it runs over a pulley 70 on the lower end of theside piece '0. Tothis cord a handlel and a footpiece p may be attached, whereby a downward pull can be exerted conveniently thereupon to produce a considerable pressureupon the side pieces, thereby causing a compression of the bag. if it is desired to, place a-particular tension upon (the bag above that given by the Weight of the apparatus, it may be done by means of a cord 9', which is secured to the lower end of one of the side pieces and is adapted to be tiedaround. a stanchion m, which is secured to the lower end of the other side piece, whereby the two side pieces maybe held at a particular angle with respect to each other to exert a certain in the embodiment of the invention shown in hig's. 3 and-d the bag is supported directly upon the side pieces, which are hinged at the a bottom. The supporting-cord 0? extends from theupper end ofone of the side pieces through" 0 in the other side piece and to hold the side pieces at a particular angle without slipping.

Upon the end of the connecting-tube s an end piece 8 of any desired construction is fitted, and such end piece is preferably provided with aftip which will not obstruct the free flow of water or other liquid therethrough. Intermediate the tip and the bagi's a reservoir, which in the present case is shown as a bottle t, said reservoir or bottle being provided to hold oil, antiseptics, and other liquids with which it may be desired to impregnate the water employed in the apparatus. in order that the water may bethus impregnated without having to flow through a device which would obstruct the free flow of the water, a connecting-piece or peculiarlyformed stopper u is employed, having a passage r) for the unobstructed flow of water, and said stopper is interposed in the connectingtube 8, as illustrated in Fig. 1 of the drawings. (Jommunicating with the passage-e through preferably two passagesw and m, respectively, is the oil, antiseptic, or other liquid contained in the bottle or reservoir. When a bottle is employed, as illustrated in the drawings, a guard-piece y is preferably provided in order to hold the stopper securely upon the bottle. in order to graduate the quantity of oil or other liquid entering the tubes from the bottle,

a valve (1 may be provided upon the under side of the cork, whereby the passages on and a: may

be so restricted that a dram, ounce, or any desired quantity of oil or other liquid may flow out of the bottle during the passage of a given quantity of water.

The operation of the apparatus, which will be readily understood from the foregoing,

may be briefly outlined as follows: The bag a is filled in the ordinary manner, a cock 2 in the bottom of the bag preventingthe escape for the time being'of thewater into the connecting-tube s. The bag may be filled full or partly full, as is desired. The filling of the bag causes the side pieces 6 and c to separate, the degree of separation depending upon the extent liQ'; which the bag is filled. The bag,

- together with its supporting-frame, is then hung up by placing'the loop in the cord d upon the supporting-hook or other support, and the syringe is then ready to be put in operation.

If a particular pressure is desired above that supplied by the weight of the bag, its coni tents, and supporting-frame, the bag may be compressed between the side pieces, which by means of the cord r can be secured at a certain angle. When everything is ready, the cock 2 is opened, and the water flows down the connecting-tube s in the usual manner. When the water reaches the connecting piece or stopper a, part of it will flow through the same .7

the bottle, thereby causing rise and flow out into the and a part into any oil therein to passage Q).

pressure or head of water at any time than is being supplied through the tip, one may grasp the handle Z or insert his foot in the stirrup 0, thereby effecting -a downward pull and a greater compression upon the bag. It will thus be seen that almost any desired pressure or head of water maybe obtained at the tip 30 of the syringe. Furthermore, it will be seen that the bag, supported as it is by the frame, does not bear, as is generally the case,,the entire weight of water contained therein, and

hence is not liable to deteriorate as quickly 5 as in the ordinary syringe. It will be noted also that the pressure established by the compression of the bag is maintained on account of the unobstructed passage from'the bag to the tip, while at the same time means 9 are provided whereby oil, antiseptics', and

other liquids may be entrained in the water as it flows from the bagto the tip.

it will be understood that the invention is not limited. to the construction shown and described herein, but that many departures may a be made therefrom without avoiding the spirit of the invention.
